Maintain sub pools within Commons pool - is it possible
Hi
We are using Apache commons pool 2.2 for pooling connection object to connect between our REST framework to Siebel Server.
Everything works fine for what I have implemented. But I want to enhance this framework. The existing implementation maintains the connection object for a particular group called ObjectManger1. Now I want to maintain the connection for multiple groups like ObjectManager1, ObjectManager2 . and so on. Is it possible to implement this kind using commons pool.
I want a subpool to be maintained for each ObjectManager_x within the commons pool
Thanks and Regards
Krishnakumar

You might be able to accomplish your goals using a KeyedObjectPool.
See the javadoc for that class.

Could you please explain, what you have in mind technically? What
would be the difference between two separate pools, and
parent/subpool?
Thanks,
Jochen

Hi Jochen,
Thanks for your message. The difference between to two separate pools is that in our framework we don't know exactly how many no of separate pool we might require, it is not two, but can scale more than 10, 20 in production environment and I think to have so many pools and that to we have to create dynamically at runtime, not practical
If it was a sub pool, I can always create the sub pool based on demand at runtime. Moreover we have few parameters for each sub pool to maintain a min and max connection objects, which parameters can be different for each sub pool and cannot be implemented while design as we do not know these value of these parameters at design time.
Please let me know if this answers your question else let know
Regards
Krishnakumar

Hi Phil,
Thanks for your message. First , how do I respond to your message. I have added the dev@commons.apache.org in this mail.
I am already using the keyedObjectPool, but the keyedObjectPool give me only one level of grouping i.e if the Key->A then I can group all the connection for A, but I need two levels of grouping i.e.
The ObjectManger1 will contain the connection for A,B,C... so with the existing implementation if I query for the Key->A then I will get the connection under ObjectManager1->A connection,
But my requirement is I want to have groups like ObjectManager1 with A,B,C ... and
ObjectManaer2 with A,B,C ...
ObjectManager3 with A,B,C and so on
So when I request for a connection for A, I have the option to choose the A from ObjectManager1, ObjectManager2, or ObjectManager3 by selecting ObjectManagerX.
Is this kind of implementation possible?
Regards
Krishnakumar
